Survey of Coolant Use in Military Ground Systems to Select Candidates for Evaluation
Abstract
Currently, U.S. Army engine coolant is governed by Commercial Item Description (CID) A-A-52624A, Antifreeze, Multi-Engine Type, which mandates the use of conventional, supplemental coolant additive (SCA) based technology. SCA based coolant lacks key advantages of the newer more widely used Organic Acid Technology (OAT) based coolant, also known as Extended-Life Coolant (ELC). ELC has been commercially available and used in passenger cars since 1995, with General Motors being the first original equipment manufacturer (OEM) to adopt OAT technology in their factory fills, but the Military has not yet adopted the use of OAT technology [1][2]. One disadvantage of SCA coolant is that it has a short life span of two years, and that is only if additives are reinhibited every six months. In 2015, the Ground Vehicle Systems Center (GVSC) learned from the U.S. Army Combined Arms Support Command (CASCOM) that the reinhibition process was not occurring at field level maintenance, and instead a full flush and refill was conducted annually. This unnecessarily increases the maintenance burden and quantity of coolant being used by the Army.
